Former U.S. Senator John Edwards and his daughter Cate Edwards (R) leave the federal court house after jury selection in Greensboro, North Carolina in this April 12, 2012 file photo. Edwards goes on trial on April 23, 2012 on charges he used illegal campaign contributions to cover up an affair with a mistress who became pregnant during his failed bid for the 2008 Democratic presidential nomination. Edwards is accused of accepting more than $900,000 in campaign funds from two wealthy donors, knowing the exposure of his extramarital affair "would destroy his presidential campaign," prosecutors said in a trial brief.
